Community and ecosystem mostly. Maybe it's changed a lot since version 3 but I don't see much uptake. I had enough issues that a rewrite of my API in Typescript was faster than upgrading to 4 when it came out. Edit: looking at the docs again theres an official upgrade guide now so thats a step int he right direction, I'll take a closer look when I get a chance.
